Salutations

Hi, sorry i posted a question in new comers area....

Just joined the site today, very happy to see a site like this to present questions for help.

I made another post, with my question.... its very simple i believe and i'm looking for confirmation about my thoughts. Just no confidence that the question was incorrectly given on a test since its been so long since i've messed with f(x) --- function? questions???--- or been in school for that matter
